About the Ortlieb Velocity Backpack This courier-style backpack has been one of ORTLIEB\\\'s most popular products for many years. It is simply unbeatable when it comes to accompanying you to work, school, and play. Some of the Velocity\\\'s distinctive features include its durability, waterproof performance and rear padding that ensures excellent ventilation. The Velocity\\\'s carriage system has now been ergonomically optimized for even greater carrying comfort. The waist belt is easy to adjust and even detachable. The Velcro roll closure makes for wonderfully easy access and packing. And if the Velcro pad should ever wear out after many years of intensive use, you can return your Velocity to ORTLIEB to have it renewed, so as to give your backpack a second life. This makes the Velocity a sustainable, lifetime companion. The backpack\\\'s interior has also been given a new design. In addition to the large zippered inside pocket, both Velocity models now have a padded laptop compartment. And the biggest \\\"new feature\\\" is the introduction of a smaller version to the Velocity line. With a volume of 17 liters, this backpack is ideal for shorter people or for all of those who simply need less space for their precious cargo. Velocity\\\'s little brother has all of the features of the big brother, only in a somewhat smaller size and a volume reduction of 6 liters. Whether big or little, the Velocity is a purchase of a lifetime!
